Thiago Tavares suspended after testing positive for a banned substance at UFC on FX 7

UFC on FX 7 happened weeks ago, but drug testing results just became public today. One fighter tested positive for a banned substance, while another was given a testosterone therapeutic use exemption.

-- Thiago Tavares, who lost to Khabib Nurmagomedov, tested positive for drostanalone. He is suspended for nine months, and will have to submit a clean drug test before he fights again. Taking a long break from fighting could hurt Tavares financially, because he only fought once in 2012.

-- Vitor Belfort received a therapeutic use exemption for the use of testosterone. The UFC said he was diagnosed with hypergonadism. Belfort tested positive for an anabolic steroid in 2006, and rumors swirled that he was the fighter who tested positive. UFC president Dana White said after Saturday's fights that it was not Belfort.

These fights were the first ones governed by Brazil's sports commission, and the testing was done by an independent lab.
